consider the first copy of an allele for insecticide resistance that arises by mutation in a population of insects exposed to an insecticide. if, after some generations, we find that most of the population is resistant and shares in this mutation, is it likely that this resistance is an adaptation?

Natural selection is the unequal survival that results from the presence or absence of particular traits.

Natural selection is the differential survival and reproduction of individual species. It is a process through which species adapt to their environment in order to survive.

The term "natural selection" itself was popularized by Charles Darwin, an English naturalist, geologist, and biologist. The term contrasts the essence of naturalism in the process, in which there is no intentional selection made (vs artificial selection).

The concept of natural selection was published by Darwin and Alfred Wallace in 1858, and since then has been one of the cornerstones of modern biology.

DNA carries the genetic code that determines the characteristics and traits of living things where the nucleus of a cell contains chromosomes made up of long chains of DNA molecules where the genes are small segments of DNA.

A chromosome is defined as a long DNA molecule that contains part or all of an organism's genetic material, which are very long thin DNA fibers that are coated with packaging proteins; The most important of these proteins in eukaryotic cells are the histones.

DNA, genes and chromosomes work together to make us where chromosomes carry DNA in cells while DNA is responsible for building and maintaining the human structure. Genes are segments of DNA that give us the physical characteristics that make us unique.

DNA (deoxyribonucleic acid) is a molecule that contains the biological instructions that distinguish each species. During reproduction, DNA and the instructions it contains are passed down from adult organisms to their offspring.

The genetic instructions passed down from generation to generation are stored in DNA.

In the nucleus of every cell in the human body is a bundle of DNA containing approximately three billion chemical nucleotides encoding approximately 30,000 genes, which are discrete chunks of DNA that are translated into individual proteins. Thousands of genes are found on each of the 46 chromosomes in the nucleus of a human cell.

Sunlight and chlorophyll play major roles in photosynthesis, when sunlight strikes a plant’s leaves the energy absorbed is used to convert it into Glucose.

Through the process of photosynthesis, light-energy is used to transform carbon dioxide and water molecules into glucose.

In addition to contributing to photosynthesis, which enables plants to manufacture their own food, chlorophyll is a pigment that gives plants their unique green color.

Plants and other living things employ a process called photosynthesis to transform light energy into chemical energy that can then be released through cellular respiration to power the organism's activities. The process of creating sugars and starches from carbon dioxide and water also known as photosynthesis stores some of this chemical energy in these molecules.

A number of control systems that operate at the organ, tissue, or cellular level work together to maintain homeostasis

Reptiles are ectothermic, which means they rely on their surroundings to control their body temperature, whereas mammals and birds do it through metabolic heat.

For example, the human body and other warm-blooded organisms maintain homeostasis by monitoring and controlling internal water levels, body acidity, and temperatures. Osmoregulation is the mechanism through which the body's water balance is regulated.

To maintain homeostasis, a multitude of control mechanisms that act at the organ, tissue, or cellular level collaborate. Some of these regulatory processes include substrate supply, individual enzyme and receptor activation or inhibition, enzyme production and breakdown, and compartmentalization.

I do not know for sure yet, but because this new species lays eggs, I am going to guess this species is a reptile. I will need make more observations to know for sure!

This new species is very interesting to observe. Its members seem naturally curious, and love investigating my hidden cameras. I might try to capture one in the future and see if I can teach it a new behavior. But for now, I don’t know if the population could afford to lose a member. They must be rare if no one has discovered one before. For now, its environment is doing well. I am seeing an increase in the butterfly population, which is allowing for an increase in the flowing plants, since the butterflies help to pollinate them.

I think I have discovered a new species! I found them while studying the area to see how a recent increase in rainstorms is affecting the environment. The change seems to have made the species more successful.

A gene is a sequence of DNA that encodes instructions for the production of a functional product, such as a protein.

Protein is an essential macronutrient found in foods such as meats, eggs, dairy, nuts, and legumes. It is composed of amino acids, which are the building blocks of life. Proteins serve many important functions in the body, including providing structure for cells, helping to make hormones and enzymes, and assisting with the transport of nutrients and waste products. They are also an important source of energy, providing 4 calories per gram. Protein is essential for muscle growth and repair, and is needed for normal growth and development. Adequate protein intake is essential for maintaining a healthy weight, as it helps to keep you feeling fuller for longer. It is also important for healthy skin, nails, and hair.

Hans Selye's General Adaptation Syndrome (GAS) is a theoretical framework that describes the body's physiological response to stress.

According to Selye, the body goes through three distinct stages in response to stress:

1. Alarm reaction: This is the initial stage where the body's alarm system is activated in response to stress. The body releases adrenaline and other stress hormones, increasing heart rate and blood pressure and preparing the body for action.

2. Resistance: This stage is characterized by the body's efforts to adapt to the stress and restore balance. Hormonal and physiological changes occur in an attempt to counteract the effects of stress.

3. Exhaustion: If the stress persists, the body's adaptation mechanisms become exhausted and the individual becomes vulnerable to illness and disease.

Selye's General Adaptation Syndrome has been widely studied and has provided valuable insights into the physiological effects of stress on the body. However, some researchers have criticized the model for oversimplifying the complex physiological and psychological responses to stress.
